Wireless Sensor Networks (WSNs) play a vital role in monitoring environmental and physical conditions, but their performance is highly constrained by limited energy resources. The Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is widely used for energy-efficient routing; however, it suffers from issues such as early cluster head (CH) failure and reduced network lifetime. To address these limitations, this work proposes an improved VLEACH protocol incorporating fuzzy logic for intelligent selection of cluster heads and vice cluster heads. The proposed approach utilizes fuzzy if-then rules based on parameters such as residual energy and node centrality to optimize the selection process. Additionally, a threshold-based mechanism is introduced to limit unnecessary vice cluster head assignments, thereby reducing energy consumption. The protocol is evaluated through MATLAB simulations using performance metrics such as network lifetime, packet transmission, and node death rate. Experimental results demonstrate that the proposed fuzzy-based VLEACH significantly enhances network lifetime and energy efficiency compared to traditional LEACH and VLEACH protocols. The first and last node death rounds are substantially improved, validating the effectiveness of the approach.
